  1. 1. Aspects of maxillary sinus reconstruction with endosseous implants

    Författare :John Eric Blomqvist; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Odontologi; Odontology; stomatology; sinus inlay bone augmentation.; osteomorphometry; osteometry; maxillary sinus reconstruction; maxilla; bone graft; Alveolar bone loss; dental implants; implant position; bone;

    Sammanfattning : This study of maxillary sinus reconstruction in conjunction with insertion of endosseous implants included 99 patients. Two separate surgical methods were applied; a one-staged strategy (n=49) and a two-staged strategy (n=50). The aims were to compare two different strategies concerning implant and prosthetic construction survival. LÄS MER

  2. 2. The peri-implant tissues from an esthetic perspective

    Författare :Moontaek Chang; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clinical; dental implants; esthetics; single-tooth replacements; soft tissues; infra-occlusion; bone alterations;

    Sammanfattning : The overall objective of the thesis was to evaluate the dimensions and position of peri-implant soft tissues in relation to the topography and alterations of the bone support, and the tissues’ significance for an esthetic appreciation of implant therapy. A comparative evaluation of crown and soft tissue dimensions between implant-supported single-tooth replacements and the contra-lateral natural tooth was made in Study I. LÄS MER

  3. 3. Assessment of acetabular cup position with computed tomography

    Författare :Henrik Olivecrona; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Background: Revision of Total Hip Arthroplasty (THA) due to loosening is necessary in many patients. Diagnosis is usually late with significant bone and soft tissue destruction. Available diagnostic techniques are either not sensitive enough or too complicated and expensive for routine use. LÄS MER

  4. 4. On the Clinical Outcome of Different Single Implant Treatment Modalities

    Författare :Björn Gjelvold; Umeå universitet Molin Thorén; Malmö universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Today there are several treatment techniques available to replace a missing tooth. Since the beginning of the 1990s, it has become increasingly common to treat individual tooth loss with dental implants. Important patient factors are survival, success, functionality, aesthetics, oral health and quality of life. LÄS MER

  5. 5. Electromagnetic Modeling and Design of Medical Implants and Devices

    Författare :Oskar Talcoth; Chalmers University of Technology; []
    Nyckelord :Magnetic Resonance Imaging; Implant Safety; Lead Heating; Pacemakers; Thin-wire Approximation; Convex Relaxation; Optimal Sensor Placement; Optimal Measurements; Helix; Sensor Selection; MR Safety; Magnetic Tracking; Fisher Information Matrix;

    Sammanfattning : This thesis covers two topics in biomedical electromagnetics: pacemaker lead heating in magnetic resonance imaging (MRI) and optimization of sensorpositions in magnetic tracking.The electromagnetic part of pacemaker lead heating during MRI is a resonant phenomenon which is complicated by, among other factors, the wide range of length scales involved in the problem.
